It's the opposite: they have shown an incredible amount of restraint in the face of overwhelming opposition and crippling sanctions from Europe and USA.
What? Well, they sure have earned those sanctions haven't they? Aggressive expansionism and annexation of foreign territories, tampering with elections in the USA, not to mention atrocious domestic policies in an effective dictatorship. They have earned those sanctions and more, indeed I think we will find in the future that dealing so softly with Russia was a mistake.
Have you seen the movie this topic is about? If not I highly encourage you to watch it. Blind nationalist attitudes like yours are what will cause the disaster it depicts.
It might surprise, and horrify you to know that a large number of high-ranking US staff think that nuclear war is winnable [1]. It makes my blood boil.
> a large number of high-ranking US staff think that nuclear war is winnable
The article [1] cites two retired generals as its examples of "senior military officers" who "might be eager to get things started in the belief that a war with Russia could actually be winnable".
The official story, of course, is that it is intended to protect against Iran. From my limited understanding of geography, Poland does not lie between Iran and the United States.
Most people don't even realize that just about the same conditions led Japan to attack during WWII. There comes a time when you keep pushing a guy, and he says, enough! No mas!
Japan invaded China in 1931, Thailand in 1941 and had attacked Hong Kong, Singapore and Malaysia. It was kind of on a roll attacking stuff before it hit the US in a way that is rather different from modern Russia.
